Introduction

Blood biochemical tests generally require fasting. A blood biochemical test is a diagnostic method that detects various components in the blood to determine the presence of disease. It measures levels of substances such as carbohydrates, lipids, hormones, and ions in the blood, thereby playing an important role in disease diagnosis and treatment.

Blood biochemistry tests generally require fasting. This is to prevent changes in various indicators in the body after eating, which may affect the test results. The specific analysis is as follows:

Blood biochemistry is a diagnostic method that evaluates the presence of diseases by measuring various components in the blood. It is a common routine examination in clinical practice, primarily including liver and kidney function, blood lipids, blood glucose, cholesterol, and other related tests. Blood biochemistry can determine the levels of carbohydrates, lipids, hormones, ions, and other substances in the blood, thus playing an important role in disease diagnosis and treatment. These tests help detect conditions such as electrolyte imbalances, liver or kidney insufficiency, hyperglycemia, and acute myocardial infarction.

Patients are advised to avoid spicy, stimulating, greasy, and overly sweet foods for at least one week before undergoing blood biochemistry tests. If any abnormalities are detected, it is important to actively cooperate with the doctor's evaluation and receive timely treatment.

How to determine if a newborn has pneumonia

Neonatal pneumonia can be diagnosed through clinical symptoms, such as whether there was meconium-stained amniotic fluid at birth, or the presence of symptoms like tachypnea and respiratory distress. Additionally, routine blood tests and blood biochemistry are needed to help identify infection and assess disease severity. Imaging studies are also required to clearly visualize any lung abnormalities.

What are the “Four Tests for Hypertension”?

The “Four Tests for Hypertension” refer to four routine examinations: blood biochemistry, peripheral blood count, serum creatinine, and urinalysis. Blood biochemistry includes measurements of serum potassium, sodium, and fasting blood glucose. Second, a peripheral blood count is required. Many patients overlook the importance of the peripheral blood count; however, this test—and its clinical implications—must be carefully considered. Some patients undergo this blood count examination.

Always feel uncomfortable in the upper abdomen

Frequent discomfort in the upper abdomen may be a normal phenomenon, or it could be caused by factors such as cholecystitis or gastric ulcer. If the cause is non-pathological, adopting healthy lifestyle habits is sufficient. However, if it is due to pathological reasons, patients may require medication or surgical treatment. It is recommended that patients promptly visit a hospital for diagnostic tests such as blood biochemistry and complete blood count to determine the exact cause.

Is it necessary to fast before a sex hormone test?

The six-item sex hormone test is often required to be performed on an empty stomach because the prolactin component can be easily affected by food intake. Eating before the test may lead to inaccurate results. Fasting ensures accurate test results and also facilitates subsequent tests such as routine blood tests, blood biochemistry, and blood glucose testing. If you have any questions, it is recommended to consult your doctor in advance.

Which department should I visit for left abdominal pain?

If a patient experiences left-sided abdominal pain, they may seek care in departments such as emergency medicine, gastroenterology, general surgery, or urology, depending on their specific condition. The patient may first visit the emergency department, where initial diagnostic tests—such as complete blood count, electrocardiogram (ECG), urinalysis, blood biochemistry, serum amylase, and abdominal ultrasound—can be performed. There are numerous potential causes of left-sided abdominal pain.

Can a person with rhinitis choke when crying?

In general, people with rhinitis may or may not experience a sensation of suffocation when crying. Rhinitis can easily cause nasal mucosal congestion and swelling, further narrowing the nasal cavity. If a patient develops rhinitis, it is recommended to promptly visit the otorhinolaryngology department at a hospital for evaluation. Tests such as complete blood count, blood biochemistry, and nasal endoscopy can help clarify the condition, and patients should actively cooperate with their doctor's treatment plan.

What does a blood chemistry test mean?

Biochemical blood tests refer to examining certain biochemical indicators in the blood through venipuncture, including liver function, kidney function, and blood lipid levels. By analyzing the concentration of various substances, these tests help determine the patient's medical condition. In addition, biochemical blood tests can also measure specific blood components such as potassium, calcium, and sodium levels, which aid in assessing the body's electrolyte balance.

Do influenza A and B require blood tests?

Whether blood tests are required for diagnosing influenza A and B depends on the patient's clinical condition. If the condition is well-controlled and there are no complications, blood tests are usually unnecessary, and diagnosis can be made through respiratory sample testing. However, if the condition is poorly controlled or complications are present, blood tests such as a complete blood count (CBC) or blood biochemistry may be needed to rule out other complications and assess the severity of the illness.
